This paper presents the application of horizontal drilling in an oilfield of Kurdistan region of Iraq. The most important developments in Petroleum industry were through drilling technology by producing more horizontal wells in the worlds since eighties. Horizontal drilling is considered as a cost-effective method for developing reserves because of continues breakthrough of hardware equipment in oil fields. The technology of Horizontal wells remains to be a remarkable enthusiasm of oil industry since they can give an attractive way to enhancing both production rate and oil recovery factor. The practice of drilling a horizontal oil well in Kurdistan region of Iraq will be highlighted in this paper. In the previous few years horizontal drilling in this region has given an exciting experience for petroleum engineers. A horizontal well will be drilled in the oil fields of Taq Taq and one of the important applications of this well is to recover production rate in thin/tight reservoir and saving in total growth cost. The aim of this paper is to show the structure and parts of horizontal well. Well plan viewpoints incorporate choice of bit and casing sizes, casing setting depths and penetrating mud density, casing, and hydraulics, technique for boring and well profile. An Iraqi oil field (Taq Taq field) is selected for designing horizontal well to increase the productivity and long rich position. Short to Medium radius horizontal well profile is suggested for the developing the field. This paper employs instructions learned and results obtained while applying a rotary drilling of an offset nearby well with liner system on conventional horizontal rig, during the designing and drilling operation arrangement. The main goal of this work is to show the impact of horizontal drilling application on the performance improvement of that oil field. [ABSTRACT FROM AUTHOR]

Delays and disruption are a common issue in both community and personal building programs The problem exists all throughout the world, but it is particularly prevalent in Iraq, where millions of dollars are squandered each time as a outcome. Delays and interruptions may have serious consequences not just for Iraq's construction plans, but also for the country's economic and social status. While numerous studies have been conducted to investigate the factors driving delays and disruption in Iraqi construction projects, slight consideration has been given to by what means project management implements and approaches have affected the occurrence of project delays and disruption. After analyzing the crucial reasons for delays and instability in public and private construction projects in Iraq, this paper aims to improve the recording and recommendations using Project Supervision concepts. A thorough investigation was conducted to identify the critical factors that are causing delays and disruptions in construction projects in Iraq's public and private sectors and present project management application procedures in order to establish recommendations to successfully reduce work disruptions and instability in Iraq This paper identifies the top crucial factors contributing to construction project delays and disruptions in Iraq. It further identifies project management Tools and techniques that, when used appropriately, have the potential to address the major causes of delays and interruptions. Following that, a new set of guidelines for applying Project Management methodologies and strategies to address the identified delay and disruption issues is provided, with the objective of aiding practitioners in minimizing the possibility for construction delays and interruption in Iraqi projects.

Relative permeability data are very important factor in characterizing the two-phase flow of fluids in porous media. It is also a key data to predict the performance of immiscible displacement in oil reservoir thus why many equations and correlations were made to predict them. This paper is to calculate and compare the results of the most common correlations used to identify relative permeability, which are Corey, modified Corey and Wyllie and Rose. The comparison was made based on real saturation data taken from two different Iraqi oil fields, the basic difference between the two fields where API value. The data from the first well (titled X-4) were taken from X oil field which is located in the southern part of Iraq, this field has heavy oil with about 20 API approximately. The data from the second well (titled Y-37) were taken from Y oil field which is located in the northern part of Iraq, this field has light oil with about 40 API. Each well was tested two times in two case studies. Results indicate that the modified Corey correlation was valid for light and heavy oils (both wells) and gives acceptable match values in all case studies, almost a perfect match in heavier oils (X-4), while Wyllie and Rose correlation gives better results in lighter oils (Y-37).

Rock porosity represents the main property that controls the fluid distribution and hydrocarbon extraction from the reservoir rock. In this study, information from five wells was integrated with post stack seismic data acquired from a 3D seismic survey of the northern part of Rumaila Oil Field to perform seismic inversion to derive porosity. The used well log data includes gamma ray, resistivity, density, acoustic impendence (from compressional velocity and density) logs, check shot, and VSP surveys, in addition to the tops of formations (which are converted to time-based logs) after performing check shot correction and generating a synthetic seismogram. Seismic inversion analysis is an attempt to correlate seismic attributes like acoustic impedance (A.I) to rock properties (porosity). The inversion analysis is used in this paper to predict the porosity distribution. 3D seismic surveys (migrated post-stack) of the northern part of Rumaila oil field and well data used for this study. Information from five wells integrated with post-stack seismic data to perform seismic inversion through the area surveyed seismically. Four horizons picked within the seismic 3D volume that Shaw maximum crest at the northern part in the field and guide initial model for low frequency in addition to using it in the extraction of slices through converted 3D A.I. and calculated porosity data, the porosity slice guided by the picked target Shaw enhancing porosity with upward direction. The zones with low A.I. in the slices extracted through A.I. volume indicate high porosity zones. Integration of well and seismic data show a more accurate distribution of reservoir property than using well data alone. [ABSTRACT FROM AUTHOR]
